TRAIN-PIPE END VALVE.

1'0 alt whom it may concern:

Be it known that I, JAMES F. MoELRoY, a citizen of the United States, and residing at Albany, county of Albany, State of New York, have invented certain new and useful Improvements in Train-Pipe End Valves, of which the following is a full, clear, and exact disclosure.

My invention relates to an improvement in train-pipe end-valves, particularly the operating devices therefor and the form thereof which I now consider the best, is illustrated in the accompanying drawing, Wherein Figure l is a side elevation, partly in section; Fig. 2 is a section of the valve; Fig. 3 is a detail of the upper end of the operat ing handle.

Referring to Fig. 2, T is the valve, which is of disk form, its open position being shown in full lines and its closed position in dotted lines. This valve is mounted on operating rock shaft B and kept from ro-' tating thereon by means of shoulders I) b. A is the valve-housing provided with a screw cap P covering an opening through which the valve may b inspected and renewed. The valve casing A is secured to the extremity of the train-pipe A Referring to Fig. 1, the valve is arranged in the position shown underneath the car platform. The shaft B is prolonged by a stem I, preferably connected to the shaft B by a gimbal joint C. This stem I is journaled in the lower end of a bracket E and is provided with crank arm or lever handle D which may be turned down to the position shown in full lines to open the valve or lifted up to the position shown in dotted lines to close it. There is also connected to that handl D a handle-bar composed of link F adjustably connected to the handle D, as shown, and a second link G jointed to F at f and projecting through the car platform where it terminates on the upper side in a loop handle mounted in the housing K. The

link G has a contracted neck near its upper end which is engaged by the dogs R R pressed against the neck of the springs S S respectively. The dogs R R serve to practically lock the handle-bar in its lowest or open position by engaging the aforesaid neck and to again lock the handle-bar in its uppermost or closed position by engaging Specification of Letters Patent.

the lower end of the link G where it is pivoted to the link F. By exerting more or less force, however, the handle-bar can be either lifted or depressed in spite of the retaining action aforesaid of the dogs R R.

I do not intend to limit myself to the specific form herein shown, for other forms may be employed within the confines of my 1nvention. g

What I claim as new and desire to secure by Letters Patent is: I 1. An operating device for a train-pipe end-valve comprising a rock shaft in operative connection with the valve, a crank arm rigidly secured at one end to said rock shaft, and a sectional yielding operating link connected at one end to the other end of said crank arm. v

2. An operating-device for a train-pipe end-valve comprising a rock shaft in operative connection with the valve, a crank arm rigidly secured at one end to said rock shaft, a sectional yielding operating link connected at one end to the other end of said crank arm, the other end of said link being provided with a handle.

3. An operating device for a train-pipe end-valve, comprising a valve-shaft, a' vertically moving handle-bar extending through the car floor and a stop for holding said bar in its depressed position.

,4. An operating device for a train-pipe end-valve, comprising a valve-shaft, vertically moving handle-bar therefor extending through the car floor, and stops for holding the bar in both its raised and closed positions.

5. An operating device for a train-pipe end-valve, comprising a horizontal shaft in operative connection with the valve, a bracket suspended from the undersurface of the car floor and in which said shaft is mounted and a vertical operating handle for said shaft extending through the car floor.

6. An operating device for a train pipe end valve comprising a horizontal operating shaft having one end connected to the valve, a bracket for supporting the free end of said operating shaft and a vertically disposed longitudinally movable handle operatively connected to the free end of said shaft.

7. An operating device for a train pipe end valve comprising a horizontal operating shaft having one end connected tojthe valve by a universal joint, a racket for su porting the free end of said operating s'ha and avertically disposed handleoperatively connected to the free end of said shaft.

8. An operating device for train {pipe end-valves comprising an o crating shaft for the'valve, "a stem, means or unlversally connecting said stem to said shaft, a lever ing for .yieldingly engaging said bar.

operating the valve from below the plat-v Fforn'i', a pivotal connection between the handle bar and the-said meansfand automatically acting means carried by the car platform for retaining the devicein the position set by either the handle bar or the valve 0p-' D crating means.

v 10. A-train-pipe end-valve provided with a horizontal operating device, two han les connected to the outer end of said device" one above and the other below the car platform,'and a yielding stop whereby; the valve may be operated by. either handleand held in the position to which it is thrown by the handle that is operated.

11. A train pipe end-valve, combined with .an operating handle below the carlplatform,

a horizontal connection between said handle and the valve, a second handle above the on platform, and a yielding stop operable by both handles.

In witness whereof I have hereunto set 40 my hand before two subscribing witnesses.
